Abstract
A voice-over-IP (VoIP) connection is established over a radio interface with a mobile radio station. A current radio condition for the VoIP connection is determined, and from that, a modulation and coding scheme (MCS) for a portion of the VoIP connection. A VoIP voice encoding mode for a portion of the VoIP connection is selected based on the determined modulation coding scheme. VoIP voice is then encoded into a number of VoIP encoded frames using the selected VoIP voice encoding mode which has an associated bit rate. An optimal number of VoIP encoded frames is included in a VoIP packet for transport over the VoIP connection given the selected voice encoding mode and the selected MCS. Other adjustments may be made to ensure robustness of the VoIP connection and/or to maximize capacity.
